Upstairs was completely full
Downstairs was way more of a dive feel and just hot as hell due to no AC and open walls.
Beer is cold and $3 each but came in a can? UGH! Hate can beer.
Was said to be a biker bar but more of the people stumbling out of the place while I was there looked more homeless than biker.. And I do mean STUMBLE.
These other reviews are spot-on.  Facing the Gulf is wonderful on any day when it's not raining, with a drink in your hand and loved ones by your side. The Poop Deck is a very small  old-school, no frills  bar, and the patrons and staff are wonderful people. Sure, you'll get a bad egg once in a while anywhere you go.  But I feel safe here, there are only people who want to have a drink and sit outside and visit.  Not a  meat market, not a pick up place, just  a run down belly-up to the bar kind of place.  It's mostly an older crowd, people that aren't looking for entertainment, but my college aged daughter definitely enjoyed herself too.
Review Source:As we were walking around Seawall on Sunday afternoon we decided to make the Poop Deck our last stop on the "Sunday Funday let's explore the neighborhood bar crawl." We walked in to the downstairs bar which wasn't really happening. We walked upstairs to find a lot of bikers on the deck upstairs and a little more going on. We ordered some drinks and tried to find a spot outside. A table opened up and we sat there and people watched for a good half hour. I am not impressed by motorcycles so when you sit there and constantly rev them up its more annoying to me than cool. Sorry, just how I feel. You get a lot of that here. Don't expect to have a nice quiet conversation at this bar, there's a lot going on.
They have a pool table and a jukebox upstairs. The pool table is missing some balls so it gave my boyfriend an advantage. It's a dive for sure, but awesome!
